Police have made another arrest in connection with the London Bridge terror attack.

Scotland Yard said a 19-year-old man is being held on suspicion of preparing terrorist acts after a raid at a property in Barking, east London, around 9.50pm on Sunday.

The address is being searched by detectives from the Metropolitan Police's Counter Terrorism Command who are also searching another property in Barking where a 28-year-old man was arrested on Saturday.

Seven men are being held in custody under terror laws following the 3 June attack that left eight dead and dozens wounded.

Police released images of the terrorists' blood-spattered fake suicide belts on Sunday which turned out to be phoney bombs made up of disposable water bottles wrapped in silver and black tape and attached to leather belts designed to create "maximum fear", Scotland Yard said.

The terrorists Khuram Butt, Rachid Redouane and Youssef Zaghba wore the fake explosive devices when they launched a van and knife rampage.

Metropolitan Police Commander Dean Haydon praised the bravery of the police officers and members of public who tackled the three despite the danger of being killed in an explosion had the vests been real.

A week after the atrocity, people returned to the Borough Market area on Saturday night - but the market is expected to stay closed for a few more days as police continue their investigation.
